Aim (aim):

A visual representation of numbers of civilization in each continent and different period of times

Visual Design Type (vistype):

Interval selection scatter plot and bar chart

Visual Mappings (vismapping):

X axis: minimum date

Y axis: maximum date

color: Depending on the continent

size of circles: existence period

Data Preparation (dataprep):

For existence period I have subtracted maxDate and minDate.

Using the coordinates provided I have tried to represent each raw with it's continent using a formula created in Excel file.

Improvements (improvements):

As some civilizations in different continents lived in the same period of time you can't visualise on the scatter plot, but you can see them on the bar chart.
